Wow this is one skinsuit I'm okay with. It just being louder layer of whatever you transformed into, I can dig that! Though of course my favorite part of the gender TF is the process, so skipping it by putting a suit on isn't optimal but anything is good. Apparently this is multi-work? I need to see the rest and of course it be translated so I can understand what's going on! Lol. I got at least that he had some kind of mind control potion that forces you to obey orders, even ones that technically a person can obey but your body transforms to do so if needed, voila busty girl.

Found part two, also raw, here:

I wish the skinsuit part wasn't there to be honest but I guess they needed a way to return.
